Transmission media lie below the physical layer. We can evaluate transmission media by throughput‚ propagation speed‚ and propagation time. * A guided medium provides a physical conduit from one device to another. Twisted-pair cable‚ coaxial cable‚ and optical fiber are the most popular types of guided media. Twisted-pair cable consists of two insulated copper wires twisted together. Twisting allows each wire to have approximately the same noise environment. Twisted-pair cable is used in
